Photo-stable cosmetic and pharmaceutical formulations containing UV-filters

ABSTRACT

A method of using compounds of formula I ##STR1## in which the C═C double bond is present in E and/or Z configuration and the variables have the following meanings: 
     R 1  denotes COOR 5 , COR 5 , CONR 5  R 6 , CN, O═S(--R 5 )═O, O═S(--OR 5 )═O, R 7  O--P(--OR 8 )═O; 
     R 2  denotes COOR 6 , COR 6 , CONR 5  R 6 , CN, O═S(--R 6 )═O, O═S(--OR 6 )═O, R 7  O--P(--OR 8 )═O; 
     R 3  denotes hydrogen, an optionally substituted aliphatic, cycloaliphatic, araliphatic or aromatic radical having in each case up to 18 carbon atoms; 
     R 4  denotes an optionally substituted aromatic or heteroaromatic radical containing from 5 to 12 ring atoms; 
     R 5  to 
     R 8  independently denote hydrogen, an open-chain or branched-chain aliphatic, araliphatic, cycloaliphatic or optionally substituted aromatic radical containing in each case up to 18 carbon atoms, 
     where the variables R 3  to R 8  may also form, together with the carbon atoms to which they are attached, a 5-membered or 6-membered ring, which may be anellated if desired, 
     as UV filters, particularly UV-A filters, in cosmetic and pharmaceutical formulations for the protection of the human skin or human hair from solar radiation, alone or together with compounds known per se in cosmetic and pharmaceutical formulations and capable of absorbing radiation in the UV range.

The invention relates to the use of enamine derivatives as photo-stable UV filters in cosmetic and pharmaceutical formulations for the protection of the human epidermis or human hair from UV radiation, specifically that ranging from 320 to 400 nm.

It is the purpose of the screening agents used in cosmetic and pharmaceutical formulations to prevent injurious influences of sunlight on the human skin or at least to reduce the effects thereof. On the other hand these screening agents also serve to protect other ingredients from destruction or degradation due to UV radiation. In hair-care formulations it is desirable to reduce damage to the keratin fiber caused by UV radiation.

The sunlight reaching the earth's surface has a concentration of UV-B radiation (from 280 to 320 nm) and UV-A radiation (>320 nm ), which follow directly on the visible light range. The effect thereof on the human skin is demonstrated by sunburn, this being particularly so in the case of UV-B radiation. Accordingly the market offers a relatively large number of substances which absorb UV-B radiation and thus prevent sunburn.

Dermatological investigations have now shown that UV-A radiation can also cause skin lesions and allergies by, for example, causing damage to keratin or elastin. This means that the elasticity and water-holding capacity of the skin are reduced, ie the skin is less supple and tends to form wrinkles. The remarkably high abundance of skin cancer in areas of strong sunshine clearly shows that damage to hereditary factors in the cells is caused by sunlight, specifically by UV-A radiation. Knowing all this, it is clear that the development of efficient filtering substances for the UV-A range is necessary.

There is a growing need for screening agents for cosmetic and pharmaceutical formulations which may primarily serve as UV-A filters and whose absorption maxima should therefore be in the range of from approximately 320 to 380 nm. In order to achieve the desired action with a minimal amount of material, such screening agents should additionally show a high degree of specific absorption.

Furthermore, screening agents for cosmetic preparations must also satisfy a large number of other demands, for example show good solubility in cosmetic oils, high stability of the emulsions prepared therefrom, toxicological acceptability and also little intrinsic odor and little intrinsic color.

Another requirement to be satisfied by screening agents is: adequate photostability. However, this is not or only insufficiently provided by the hitherto available screening agents for the absorption of UV-A radiation.

In French patent specification No. 2,440,933, 4-(1,1-dimethylethyl)-4-methoxy-dibenzoylmethane is described as a UV-A filter. It is proposed therein that this specific UV-A filter, which is sold by GIVAUDAN under the trade name "PARSOL 1789", be used in combination with UV-B filters in order to absorb all of the UV radiation having a wavelength from 280 to 380 nm.

However, this UV-A filter, when used alone or in combination with UV-B filters, is not sufficiently photochemically stable to ensure constant protection of the skin during a lengthy sunbath, which makes it necessary to re-apply it to the skin at regular short intervals, if it is desired to achieve effective protection of the skin from the entire range of UV radiation.

EP 0,514,491 therefore proposes that the insufficiently photo-stable UV-A filters be stabilized by the addition of 2-cyano-3,3-diphenylacrylates, which are themselves active as filters for the UV-B range.

Furthermore, EP 251,398 has already proposed that chromophores that are capable of absorbing UV-A radiation and UV-B radiation be combined to a single molecule by a connecting link. This suffers from the drawbacks that free combination of UV-A filters and UV-B filters in cosmetic formulations is no longer possible and that difficulties encountered in chemically linking the chromophores permit the use of only certain combinations.

It is thus an object of the present invention to propose screening agents for cosmetic and pharmaceutical purposes which achieve high absorption in the UV-A range and which are photo-stable, have little intrinsic color ie exhibit a well-defined band structure and are soluble in oil or water depending on the substituent incorporated.

This object is achieved, according to the invention, by the use of compounds of Formula I ##STR2## in which the C═C double bond is present in E and/or Z configuration and the variables have the following meanings:

R¹ denotes COOR⁵, COR⁵, CONR⁵ R⁶, CN, O═S(--R⁵)═O, O═S(--OR⁵)═O, R⁷ O--P(--OR⁸)═O;

R² denotes COOR⁶, COR⁶, CONR⁵ R⁶, CN, O═S(--R⁶)═O, O═S(--OR⁶)═O, R⁷ O--P(--OR⁸)═O;

R³ denotes hydrogen, an optionally substituted aliphatic, cycloaliphatic, araliphatic or aromatic radical having in each case up to 18 carbon atoms;

R⁴ denotes an optionally substituted aromatic or heteroaromatic radical containing from 5 to 12 ring atoms;

R⁵ to

R⁸ independently denote hydrogen, an open-chain or branched-chain aliphatic, araliphatic, cycloaliphatic or optionally substituted aromatic radical containing in each case up to 18 carbon atoms,

where the variables R³ to R⁸ may also form, together with the carbon atoms to which they are attached, a 5-membered or 6-membered ring, which may be anellated if desired,

as UV filters, particularly UV-A filters, in cosmetic and pharmaceutical formulations for the protection of the human skin or human hair from solar radiation, alone or together with compounds known per se in cosmetic and pharmaceutical formulations and capable of absorbing radiation in the UV range.

We prefer those compounds of formula I, in which R³ stands for hydrogen, R¹ for CN, COOR⁵ and COR⁵ and R² for CN, COOR⁶ and COR⁶, where R⁵ and R⁶ independently denote open-chain or branched-chain aliphatic or optionally substituted aromatic radicals containing up to 8 carbon atoms.

We particularly prefer the use of compounds of formula I in which R³ stands for hydrogen, R¹ for CN, COOR⁵ and COR⁵ and R² for CN, COOR⁶ and COR⁶, where R⁵ and R⁶ independently denote open-chain or branched-chain aliphatic or optionally substituted aromatic radicals containing up to 8 carbon atoms and R⁴ stands for an optionally substituted aromatic or heteroaromatic radical containing up to 10 carbon atoms in the ring, particularly a substituted phenyl, thienyl, furyl, pyridyl, indolyl or naphthylene radical and more preferably stands for an optionally substituted phenyl or thienyl radical.

Suitable substituents comprise both lipophilic and hydrophilic substituents containing, eg up to 20 carbon atoms. Lipophilic radicals, ie radicals which improve the oil-solubility is solubility of the compounds of formula I are, for example, aliphatic or cycloaliphatic radicals, particularly alkyl radicals containing from 1 to 18 carbon atoms, alkoxy, monoalkylamino and dialkylamino, alkoxycarbonyl, monoalkyl- and dialkyl-amino-carbonyl, monoalkyl- and dialkyl-aminosulfonyl radicals, and also cyanogeno, nitro, bromo, chloro, iodo or fluoro substituents.

Hydrophilic radicals, ie radicals which make the compounds of formula I soluble in water, are, for example, carboxy and sulfoxy radicals and particularly their salts with any physiologically acceptable cation, such as the alkali metal salts or the trialkylammonium salts, such as tri(hydroxyalkyl)ammonium salts or 2-methyl-propan-1-ol-2-ammonium salts. Other suitable radicals are ammonium, particularly alkylammonium, radicals containing any physiologically acceptable anion.

Suitable alkoxy radicals are those containing from 1 to 12 carbon atoms, preferably those having from 1 to 8 carbon atoms.

Specific examples thereof are:

Suitable monoalkylamino or dialkylamino radicals are for example those containing alkyl radicals having from 1 to 8 carbon atoms, such as methyl, n-propyl, n-butyl,

2-methylpropyl, 1,1-dimethylpropyl, hexyl, heptyl, 2-ethylhexyl, isopropyl, 1-methylpropyl, n-pentyl, 3-methylbutyl, 2,2-dimethylpropyl, 1-methyl-1-ethylpropyl and octyl. These radicals are also present in the monoalkyl- and dialkylaminocarbonyl radicals and the corresponding sulfonyl radicals.

Alkoxycarbonyl radicals are eg esters which contain the aforementioned alkoxy radicals or radicals of higher alcohols, eg, those containing up to 20 carbon atoms, such as iso-C₁₅ -alcohol.

The invention also relates to the novel compounds of formula II, ##STR3## in which the C═C double bond is present in E and/or Z configuration and in which X denotes a cyanogen radical or COCH₃, R⁴ denotes a phenyl radical which, when X is CN, may be substituted by one or more alkyl, alkoxy, alkylaminocarbonyl or alkoxycarbonyl radicals, containing in each case up to 20 carbon atoms, or cyanogen or carboxy radicals, and also by water-soluble substituents selected from the group consisting of carboxylate, sulfonate or ammonium radicals, for example alkali metal carboxylate or carbonyloxytri(hydroxyethyl)ammonium or sulfonyloxytri(hydroxyethyl)ammonium radicals, or, when X is COCH₃, may be substituted by one or more alkoxy radicals containing up to 20 carbon atoms or alkoxycarbonyl radicals containing 4 to 20 carbon atoms, and also by water-soluble substituents selected from the group consisting of carboxylate, sulfonate or ammonium radicals, and R⁵, when X is CN, denotes a C(CH₃)₃ radical or, when X is COCH₃, an open-chain, branched-chain or cyclic alkyl, alkoxy, or alkoxyalkyl group containing in each case up to 18 carbon atoms, or an aryloxy group.

The compounds of formula I to be used in the present invention may be prepared by condensation according to the following equation: ##STR5## in which R¹ to R⁴ have the meanings specified above.

For example, the reaction of 2,4-pentanedione with 2-ethylhexyl anthranilate and triethyl orthoformate gives compound 24 in Table 2.

The cosmetic and pharmaceutical formulations containing screening agents are usually based on a carrier containing at least one oily phase. Alternatively formulations based on water alone are possible when using compounds containing hydrophilic substituents. Accordingly oils, oil-in-water emulsions, water-in-oil emulsions, creams and pastes, protective lipstick compositions or grease-free gels are suitable types of formulation.

Such sun-shading preparations can accordingly exist in liquid, pasty or solid form, for example as water-in-oil creams, oil-in-water creams and lotions, aerosol foaming creams, gels, oils, grease sticks, powders, sprays or aqueous alcoholic lotions.

Common oily components used in the cosmetics industry are for example liquid paraffin, glyceryl stearate, isopropyl myristate, diisopropyl adipate, cetylstaeryl 2-ethylhexanoate, polyisobutene, vaselines, caprylic/capric triglycerides, microcrystalline wax, lanolin and stearic acid.

Common cosmetic auxiliaries which are suitable for use as additives are, for example, co-emulsifiers, greases and waxes, stabilizers, thickeners, biogenetically active substances, film formers, perfumes, dyes, pearl-lustering agents, preservatives, pigments, electrolytes (eg magnesium sulfate) and pH regulators. Suitable co-emulsifiers are preferably known water-in-oil emulsifiers and also oil-in-water emulsifiers such as poly(glycerol ester)s, sorbitan esters or glycerides. Typical examples of greases are glycerides; examples of suitable waxes are, inter alia, beeswax, paraffin wax or microwaxes optionally in combination with hydrophilic waxes. Stabilizers that can be used are, for example, metal salts of fatty acids such as magnesium, aluminum and/or zinc stearate. Suitable thickeners are for example cross-linked poly(acrylic acid)s and their derivatives, polysaccharides, particularly xanthan-gum, guar-guar, agar-agar, alginates and tyloses, carboxylmethylcellusose and hydroxyethylcellulose, also fatty alcohols, monoglycerides and fatty acids, polyacrylates, poly(vinyl alcohol) and poly(vinyl pyrrolidone). By biogenetically active substances we mean, for example, plant extracts, protein hydrolysates and vitamin complexes. Commonly used film formers are for example hydrocolloids such as chitosan, microcrystalline chitosan or quaternized chitosan, poly(vinyl pyrrolidone), poly(vinyl pyrrolidone-co-vinyl acetate)s, polymers of the acrylic acid series, quaternary cellulose derivatives and similar compounds. Suitable preservatives are for example formaldehyde solution, p-hydroxybenzoate or sorbic acid. Suitable pearl-lustering agents are for example glycol distearates such as ethylene glycol distearate, and also fatty acids and fatty acid monoglycol esters. The dyestuffs used may be any of the substances which are suitable and licensed for cosmetic purposes, as listed, for example, in "Kosmetische Farbemittel" issued by the Farbstoffkommission der Deutschen Forschungsgemeinschaft and published by Verlag Chemie, Weinheim, 1984. These dyestuffs can be used in concentrations usually ranging from 0.001 to 0.1 wt %, based on the total mixture. The total concentration of the auxiliaries and additives can be from 1 to 80 and preferably from 6 to 40wt% and the non-aqueous content ("active substance") may be from 20 to 80 and preferably from 30 to 70 wt %--based on the agents used. The preparation of the agents can be carried out in known manner, ie for example by hot, cold, hot/cold or PIT emulsification. This involves a purely mechanical process in which no chemical reactions take place.

Finally, other known substances capable of absorbing radiation in the UV-A range may be additionally used provided they are stable in the overall system embracing the combination of UV-B and UV-A filters to be used in accordance with the present invention.

The present invention also relates to cosmetic and pharmaceutical formulations containing from 0.1 t o 10 wt, preferably from 1 to 7 wt, based on the total weight of the cosmetic and pharmaceutical formulation, of one or more compounds of formula I together with compounds acting as UV screening agents known to be suitable for cosmetic and pharmaceutical formulations, the compounds of formula I usually being used in smaller amounts than the UV-B-absorbing compounds.

The major portion of the screening agents in the cosmetic and pharmaceutical formulations serving to protect the human epidermis consists of compounds which absorb UV light in the UV-B range, ie radiation ranging from 280 to 320 nm. For example, the content of UV-A absorber used in accordance with the present invention is from 10 to 90 wt % and preferably from 20to 50 wt %, based on the total weight of UV-B and AV-A filter substances.

Suitable UV filter substances which can be used in combination with the compounds of formula I used in accordance with the invention are any desired UV-A and UV-B screening substances. Specific examples thereof are:

General manufacturing instructions for the preparation of emulsions for cosmetic purposes

All oil-soluble components are heated in a stirred boiler at 85° C. When all of the components have melted or exist as liquid phase, the aqueous phase is incorporated whilst effecting homogenization. Stirring is continued while the emulsion is cooled to approximately 40° C., scented, homogenized and then cooled to 25° C. with constant stirring.
